UNITED STATES CLAES IVM. BOMAN, OF NEW YORK, N. Y.

SPECIFICATION forming part of Letters Patent No. 396,530, dated January 22, 1889.

Application filed September 14, 1888. Serial No. 285,411. (No model.)

To all whom it may concern.-

Be it known that I, CLAES WM. BOMAN, of the city, county, and State of New York, have invented certain new and useful Improvements in Cigar-Trimming Machines, of which the following is a specification.

In the manufacture of cigars it is customary, as one of the finishing operations after the cigar has been wrapped, to trim or cut off square that end of the cigar which is to be lighted.

It is my object to produce a machine for this purpose in which handling of the cigar is avoided and the work is performed automatically in great measure as to the feeding, delivering, cutting, and discharging opera tions.

The mechanism I have devised is characterized mainly by the combination of a moving endless bed provided with pockets for the reception of individual cigars and adapted and arranged to deliver and present said cigars to the action of the cutter, a cutter by which the ends of the cigars thus successively presented are trimmed, and a yielding presser by which the cigars are held firmly'in place in their pockets in the endless bed until after they have been operated upon by the cutter. In connection with the instrumentalities just recited I prefer also to use afeed trough or hopper from which the cigars one by one are delivered and taken up by the moving endless bed and a gage plate or disk by which the position of the cigars in the machine is defined and determined.

The several members of the combination may be constructed and arranged in various ways well known to the skilled mechanic without departure from my invention.

111 the accompanying drawings, to which reference will now be made in order to more fully explain the invention, I have represented that form and arrangement of mechanism which I at present prefer as being on the whole the most simple and efficient.

In the drawings, Figure 1 is a side elevation of the machine, omitting the feed hopper or trough. Fig. 2 is an end elevation looking at the cutter end of the machine.

A suitable frame or table, A, supports the working parts. On it are erected standards B, which furnish bearings for a horizontal shaft, 0. This shaft is driven from a driving-shaft, D, by a pinion, 1, on the drivingshaft meshing with the spur-wheel 2 on the shaft 0. The endless bed in this instance is formed of two wheels or disks, E, fixed to the shaft 0 at such distance apart that they will support the cigars at or near the ends thereof. These disks or wheels are recessed on their peripheries in order to form pockets to for the reception of individual cigars.

Fixed to shaft C just beyond that end of the moving endless bed from which project the ends of the cigars to be trimmed is a pcripherally scalloped or recessed steel shearing-wheel, F. The peripheral recesses 19 correspond and register with the pockets at in the next adjoining disk E. Co-operating with the shearing-wheel is a knife, G, the acting face of which runs in contact with the outer face of the shearingwheel. These two parts, the knife and the shearing-wheel, constitute the cutter. The knife may be either stationary or movable. In the present instance it is a circular rotary knife mounted on a shaft, H, driven from shaft D by belt and pulleys 3 4. (See dotted lines in Fig. 2.)

Overhanging the moving endless bed is a feed trough or hopper, I, from which the cigars are delivered one by one to the pockets a as they successively pass beneath the delivery end of the hopper. Cigars, (lettered 0,) are shown in Fig. 2 both in the hopper and in the pockets. The feed-hopper is omitted from Fig. 1 in order to avoid obscuring other parts of the machine. It is supported by a suitable bracket, I, attached to the frame. In contiguity to that end or side of the feedhopper where the tips of the cigars are is a gage plate or disk, J, fixed to the shaft C. The tips of the cigars, as seen in Fig. 1, are pressed or shoved up against the face of the disk before they reach the cutter, thus cansin g the finished cigars to be of uniform length. That face of the gage disk or plate against which the cigar-tips are pressed is cloth-faced or otherwise made yielding or soft enough not to injure the tips.

The yielding presser hereinbefore referred to consists in the present instance of an endless rubber band, K, which runs on three rollers or idlers, cl, mounted in a stand, L, attached to the frame and so placed with relation to one another and to the endless moving bed that the portion of the band next to the bed will be pressed with yielding pressure against the cigars contained in the pockets in. said bed, said pressure being greatest at the point Where the cigar is acted on by the cutter and continuing until after the trimming operation is completed, after which the cigars as they are successively carried by the endless moving bed beyond the presser are free to drop from the pockets into any suitable receptacle or leading-0d trough, M, provided for that purpose.

The mode of operation of the machine has ing of a yielding endless belt which moves by reason of its frictional contact with the cigars, the shearing-Wheel movin in unison with the endless bed and provided with peripheral recesses b, and the knife G, co-operating with said shearing-wheel, as and for the purposes hereinbefore set forth.

2. The combination of the power-driven endless bed provided with pockets for the reception of individual cigars, the yielding presser actuated by contact with the cigars, the gage plate or disk placed at one end of the endless bed and moving in unison therewith, the shearin g-wheel located at the other end of said bed, and also moving in unison therewith, and the co-operating knife G, substantially as and for the purposes hereinbefore set forth.

In testimony whereof I have hereunto set my hand this 12th day of September, 1888.
